X-amz-meta-uuid: This field is a bit of a bizarre one, as far as I can tell this field is required and it’s required to have the following value of “14365123651274”.Three weeks ago, Collabora Online moved to its new home on GitHub, and started settling in the new infrastructure, expanding its fantastic community, and continuing the work to deliver the latest and greatest developments in productivity and collaboration together. When the last parameter in this condition is an empty string “” that means anything goes and this condition will be satisfied as long as there is a key field.Īcl: The acl (Access Control List) field determines the visibility of the uploaded object. For example, the “starts-with” “key” requires that the html form containing the “key” value must in fact start with whatever is specified in the last parameter (ex. Starts-with: The starts-with condition allows one to define a restriction for a field in the post upload form. Success_action_redirect: This success action redirect field specifies where you would like S3 to redirect after a successful upload. This field is required to ensure the upload goes to the correct bucket. Anything not met will automatically cause a failure by the AWS S3 API.īucket: The bucket field is the top most name of your S3 folder structure. This is an array which describes the conditions that must be met in order for the post upload to succeed. For a more tightened approach depending on your needs you could set it to seconds, minutes or hours.Ĭonditions: Next, let’s look at the conditions field. Any easy way to handle this for example would be to take to current date time and add one day to it, allowing for a period of twenty four hours to upload the file. This field describes how long the transaction should live for. So now the fun, let’s walk through exactly what in tarhooty is going on above.Įxpiration: The first thing you’ll probably notice is the expiration field. In Go, I’ve defined the function for the sake of this post as the following.įunc AwsEncode(key, value byte) byte , We are going to be using this function over and over again throughout this post. The first thing we are going to want to do is create a function for handling HMAC SHA 256 encryption.

Just in case however, I will precede each with pseudo code so that it may be portable to other languages where needed. If you’re using Go, then the following examples are going to be perfect for you, if you’re using a different language, then there’s probably already another working sample out there for you to use.

However, through perseverance and a lot of trial and error, I figured it out. Reading through outdated docs and non-working samples are enough to make any seasoned programmer want to rage quit after a time. Now I found this to be the most tiresome and time consuming part of the process. Getting Startedįirst and foremost before anything gets posted to S3 you need to ensure that you can create an S3 signature properly. So is there a better way? Of course there is, and here’s how I did it. This brought about some obvious challenges including but not limited to showing a progress bar or spinner during upload, the fact that the file needed to be posted directly to S3 also initially meant that any errors that were going to be displayed would be ugly S3 provided (and rather abrupt) XML messages. I recently ran into a situation that required files to be directly posted to S3 without using an intermediate machine as a middleman.
